HS 290949 Other

What products does HS 290949 cover?

This subheading covers ethers-alcohols, ethers-phenols, ethers-alcohol-phenols, peroxide-alcohols, peroxide-ethers, peroxide-ketones (whether or not chemically defined), and their halogenated, sulphonated, nitrated or nitrosated derivatives, specifically those not elsewhere specified or included within other subheadings of Heading 2909. As per the Harmonized System Nomenclature, this "Other" residual subheading captures organic chemicals possessing both an ether functional group and another specified oxygen-containing functional group, provided they are not more specifically described by other 6-digit codes under 2909, such as diethyl ether or methyl tert-butyl ether. This includes a diverse range of complex organic compounds that meet the general description of Heading 2909 but lack a dedicated 6-digit classification. Official definitions from the USITC Harmonized Tariff Schedule and EU TARIC confirm this scope for residual ether derivatives.

What falls outside HS 290949?

The following products are excluded from HS 290949: simple ethers, such as diethyl ether (2909.11) or methyl tert-butyl ether (MTBE) (2909.19), which are classified under more specific subheadings within Heading 2909. Furthermore, cyclic ethers, like tetrahydrofuran (2932.11) or 1,4-dioxane (2932.99), are excluded as they fall under Chapter 29, Heading 2932, which covers heterocyclic compounds with oxygen hetero-atom(s) only. Similarly, peroxides of inorganic acids and their salts are classified under Heading 2847, not here. Compounds where the ether function is secondary to another principal function, such as certain pharmaceuticals or agrochemicals, might be classified under other chapters or headings based on their primary use or chemical structure, following the General Interpretative Rules (GRI).

What are common classification mistakes for HS 290949?

A common error is misclassifying simple ethers or cyclic ethers into HS 290949, overlooking the more specific subheadings available. For instance, classifying diethyl ether here instead of 2909.11. Another frequent mistake involves failing to correctly identify the principal function of a multi-functional compound, leading to incorrect placement. If a compound contains an ether group but its primary characteristic is, for example, that of an alcohol or a phenol, and it is specifically provided for elsewhere, it should be classified accordingly. Importers sometimes neglect to apply General Interpretative Rule 3(a) or 3(b) when a product appears to fall under two or more headings, leading to an incorrect residual classification under "Other" when a more specific provision exists. Thorough chemical analysis is crucial to avoid these errors.

How should importers classify products under HS 290949?

The correct procedure for classifying products under HS 290949 involves a systematic approach. First, identify the chemical structure and functional groups present in the compound. Confirm the presence of an ether group alongside an alcohol, phenol, or peroxide group. Second, consult the WCO Harmonized System Explanatory Notes for Heading 2909 to understand the scope and exclusions. Third, meticulously review all other 6-digit subheadings within Heading 2909 to ensure the product is not more specifically described elsewhere. If no other subheading precisely covers the product, and it meets the general description of ethers-alcohols, ethers-phenols, etc., then HS 290949 is the appropriate classification. Importers and customs brokers should always maintain detailed chemical specifications, Safety Data Sheets (SDS), and manufacturing process descriptions to support their classification decisions and be prepared for potential customs inquiries.
